probe, having a connection with the movable forcedout; and the further object of this invvention is to forma scraper having one face serrated and adapted to enter apnncture in a pneumatic tire and scrape'the'innersurface thereof adjacent thelopening.

ln tho accompanying drawings, liigurelis a side representationof my improved cementreceptacleand scraper. Fig. 2 is a lengthwise central section ofthe saine. Fig is a' length--v wise central section showing the valve in its open position. Fig. 4C is a lengthwise central "section showing the valve closed and the piston moved toward the outlet-opening. Figo is an isometrical representation of the scraper Fig. 6 is a representation ot the end of the cement-receptacle.

ln nlending pnnctures in single-tube pneumatic tires it is absolutely necessary to scrape oit the inner coating of the tire,and the lack of means for accomplishingl this has been the failure of this class ot' tires; and my object' is to provide means whereby the inner face of the tire can be scraped and the scraped surface. thoroughly coveredwith cement' be-4 fore'the patch is placed in position,

' The cement-receptacle consists o f a'fsection of tubing 1,`l1aving one end' screw-threaded alnd its other-end provided-.with lengthwise s its 2. screwed a nozzle 3having a central opening 4, its outer end being contracted, and at the outer end of the nozzle extends a foot 5,*its in.- ner face providedwith serra'tions 6. -Over the tubnlarsectionis placed a collar 7, capable of sliding thereon.

Within the open end of the tubular section is located a cap 8, having a tubular extension i), and from the'center of the cap extends an ,Upon the screwethreaded end is,

eXternall'y-screw-threaded rod l0, having a central Vopening 11 extending a portieri of its length. The free end 12 of this rod is reduced in diameter, forming a needle-valve. A piston 13 is located within the tubular section and fits very closely. With the parts in thel positionv shown at Figs. 1 and 2 `the piston is located about. midway of the length of the tubular section, and the screw-threaded rod is seated. against the inner end of the nozzle portiona-nd the end of the needle-vaive seated in the end. of the nozzle, closing the outlet, the cap being against the end of the tubular secv tion, and in such'position` the receptacle is closed.

Wheni't isdesired to force cement from vthe receptacle, the collar 7 is moved intoi the position shown at Fig. 3, which will liberate thecap by allowing the end of the tubular section to expand. The cap is then turnedtothe left hand, which will -canse the screw `threaded shaft to moveoutward, the 'piston remaining stationary... This movement will withdraw the end ofthe shaft from its seat against the inner face of the nozzle, also the needle-valve from its seat, and when the re'- quired distance has, been attained the cap, screwthreaded.rod,and piston are moved toward the discharge end ot the receptacle nntil the valvescoine in contact with their seats, when the partsw-ill'appear as shown at Fig. 3. This movement 'willoroe cement ont of the outlet, and -theqnantity discharged will depend upon the movement `of the piston. The piston is held'frorn rotation by .trictional section, andthe valvesja're held against their A seats by the collar compressing the end of the 'tubular section against thecap extension: i The central leng-'tfhfwise opening l1 in the screW-threadedsh'at is formed bto :receive a probe 14, used tofinsert 'patches through an opening in tlletire, said" probe forming the subjectfmatter ot a separate application. The probe may be withdrawn from the opening and held in connection withthe cap, as shown at Fig. 6, thereby forming a handle for 'the probe.. l The foot 5 is inserted through theA puncture in the tire and is rotated in contact with the=inner surface of the tire adjacent the opening,` the serrated surface removing the inner coating of the tire. The cementis then discharged from lthe receptacle onto the foot/and the foot again' inserted through the opening and rotated therein,wl1ich will spread the cement over the inners'nrface of the tire, and the serrated surface will cause it to work int'the fiber of the tire, the foot being removed and the 'patch 'placed into position by the employment of the probe. -To ll the receptacle, the nozzle .portion is reinoved.-
